Abstract: The invention relates to a switchgear cabinet or a switchgear cabinet assembly comprising at least one monitoring device (UST) arranged therein for monitoring switchgear cabinet functions including temperature regulation. The aim of the invention is to provide extended control options for the safety of the switchgear cabinet, whilst maintaining its ease of use. To achieve this, the monitoring device (UST) is connected by means of a link (L1) to a monitoring module (M1) of a computational unit (C1), which is responsible for external functions and is housed in the switchgear cabinet or assembly, and is configured for evaluating signals received from the monitoring module.

Abstract: A switchgear cabinet monitoring arrangement with a control device for monitoring switchgear cabinet functions, including a door position, and for generating monitoring signals for signaling to and/or controlling components relating to the switchgear cabinet functions and installed in the switchgear cabinet or on the switchgear cabinet. A simple and compact design is achieved because the control device is limited to monitoring preselectable threshold values, a door position switch is installed on or in the device housing, and the device housing has one or several indicator elements which react with a visual or acoustic indication when at least one threshold value is upwardly or downwardly exceeded.

Abstract: The invention relates to a cupboard monitoring device, for fitting in a cupboard (20), comprising a rack or a rack-like folded structure and for monitoring and control of functions affecting the cupboard itself, including a temperature monitoring and a temperature regulation, by means of a monitoring unit, arranged within a housing, comprising a housing upper piece (1.1) and housing lower piece (1.2), with connected sensors (3.1, 3.2, 3.3, 3.4, 4, 5.1, 5.2, 6). An advantageous equipping of a cupboard with the cupboard monitoring device can be achieved whereby the housing is embodied as a roof unit (1), with fixing holes arranged in the boundary region thereof for connection to the rack or the rack-like folded structure, whereby at least one part of the sensors (3.1, 3.2 ,3.3, 3.4, 4., 5.1, 5.2, 6) are arranged on the underside of the housing lower piece (1.2), facing the cupboard interior.

Abstract: The invention relates to a switch cupboard or a switch cupboard arrangement comprising at least one monitoring device (3) for switch cupboard functions including temperature regulation arranged therein. The invention is constructed in a simple manner and provided with multiple monitoring possibilities, whereby the monitoring device (3) is connected to another server-switching device(1), which is arranged in the switch cupboard or the switch cupboard arrangement in a data transmission link. The monitoring device (3) in configured in such a way that it can detect operational data from the server-switching device (1) and/or provide display information on a display control device (2) associated with the server-switching device (1), and/or record configuration data inputted via the display control device (2).

Abstract: A switchgear cabinet having at least one cabinet door and a fan-assisted air circulation on an interior for cooling heat-generating devices installed inside, which are disposed one above the other in tiers. With particular air circulation, the partial cooling air flows in the tiers and can be set and adjusted, to a large extent independently of one another.

Abstract: The invention relates to a switchgear cabinet air conditioning device comprising at least one cooling device (1), which has a cooling device control and an operating device connected thereto. A simple operability is attained due to fact that the operating device comprises a server (1.1), which is assigned to the cooling device control, and comprises a network connection as well as at least one personal computer (2), which is connected via said network connection and via a universally accessible network (3) and provided with an assigned web browser (2.1), by means of which the data retrieved from the server (1.1) can be visually displayed.

Abstract: A switchgear cabinet monitoring arrangement having a base monitoring device which is arranged or intended to be arranged in a switchgear cabinet and has at least one bus connection, several sensor connections and at least one triggering connection, for monitoring, controlling and/or regulating switchgear cabinet functions. Various monitoring and control functions of several different switchgear cabinets, along with a relatively simple construction, are achieved because a further monitoring device arranged or to be arranged in a respective further switchgear cabinet is assigned to the base monitoring device, which is connected to the base monitoring device by a field bus. The further monitoring device also has several sensor connections and at least one triggering connection and is designed for monitoring, controlling and/or regulating switchgear cabinet functions.

Abstract: A switchgear cabinet having at least one cabinet door and a fan-assisted air circulation on an interior for cooling heat-generating devices installed inside, which are disposed one above the other in tiers. With particular air circulation, the partial cooling air flows in the tiers and can be set and adjusted, to a large extent independently of one another.

Abstract: The invention relates to a control box with monitoring and control modules for statuses of built-in and/or fitted components thereof. Adaptions for various operative requirements with a comprehensible construction is achieved in that there is a central control device which can be connected via inputs and outputs to the monitoring and/or control components and by means of which the statuses of the various built-in and/or fitted components can be individually monitored, controlled and/or regulated in a predetermined or predeterminable manner.

Abstract: A switchgear cabinet monitoring and control arrangement with several switchgear cabinet monitoring and control devices connected to a network, and with at least one personal computer, which is in communication with the devices through the network. Simple operation is achieved because the at least one personal computer is connected to the network by a web browser. A server is assigned to a group of the switchgear cabinet monitoring and control devices, in which a management device containing information regarding the switchgear cabinet monitoring and control devices stored therein and including their respective identification, is arranged. The information can be called up using the at least one personal computer.

Abstract: A fan cooler for electric or electronic sub-assemblies having a control circuit with a control stage for controlling the speed of rotation of a fan motor connected to the control stage depending on set values. To achieve a polyvalent operation with a simple design, the fan motor is a phase-controlled asynchronous motor, the control circuit has a microcontroller that controls the control stage, an optic coupler is connected between the control stage and the microcontroller, and the microcontroller determines the operating angle for controlling the fan motor on the basis of the set values and the zero crossing of a control signal.

Abstract: A switchgear cabinet with a central control device for monitoring and controlling built-in units and/or attached units of the switchgear cabinet in a predetermined manner. A simple adaptation to various requirements is offered here, because central control device has components of a personal computer, through which it is programmable and by means of which monitoring, control and/or regulation takes place in accordance with predetermined programs.

Abstract: A switchgear cabinet monitoring installation, wherein a switchgear cabinet has at least one control device for units built-in or units attached to the switchgear cabinet, and at least one server. A rapid detection and reaction to a failure of the network is achieved with each control device and each server being connected via the network with a lead computer, wherein the control devices are coupled through additional connections with the lead computer and via connectors with the servers. In case of a failure of the network, the data exchange between the control devices and the lead computer can be established via the additional connection.
